18-year-old high schooler boards flight alone, leaving mom, stepfather, and 3 and 6-year-old half-siblings behind: 'I was basically expected to take over my mom's part of the parenting'

When this 18-year-old boarded an airplane alone, she knew exactly how it would impact her family, but she still chose to fly on her own. 

In many families, the eldest sibling is expected to take on the burden of caring for the younger kids. In this 18-year-old's case, that means her 3 and 6-year-old siblings — ages that are notoriously exhausting to care for. At 6, kids are usually pretty well-behaved, and they may even be in their "helpful" stage, which is both cute and makes life easier for the caregiver. But at age 3, kids are still bouncing off the walls, possibly potty-trained but also possibly still in diapers, and they're going to be racing around at full speed. All you can do is try to chase that little one as they dart around the crowded airport while you carry their luggage and hold hands with the 6-year-old! It's no wonder this teen was reluctant to take on babysitting duties from her mom. 

As she shared in her story below, she got back at her family by simply boarding the flight while they made a last-minute bathroom run. It's odd that they stayed in the bathroom for so long that they missed their boarding call altogether, but for this teen, it was totally a blessing in disguise. Commenters also agreed that she did the right thing — and that setting hard boundaries is a good thing, even if it stuns her Mom and stepfather.

    I'm 18f and in highschool, currently traveling for the holidays. I was supposed to fly down with my mom, her husband Phil, and my young half siblings (3 and 6 years old) to spend Christmas with my maternal grandparents. We live in California and my grandparents

    live in Wisconsin, so we don't see them very often, and when we do we fly. This was my half siblings' first time flying, and they didn't handle the airport well at all, and my mom and Phil handled them even worse.

    They screamed and cried the whole time, and I was basically expected to take over my mom's part of the parenting because she's pregnant, which I mostly did without complaint. Right before our boarding group was called (the last boarding group since we're not rich Imao) my mom ran off to use the bathroom.

    I waited with Phil and the kids until last call, but my mom still wasn't back, so I left them behind and boarded. I offered to take the kids with me if Phil wanted to stay back for my mom, but he insisted that the family had to stay together. I went to board but he grabbed my arm and took this fatherly tone that he freaking

    knows I hate, and basically ordered me to stay with him and the kids. I boarded anyway and left them all behind. I was really looking forward to spending time with my grandparents, and I honestly couldn't care less what Phil tells me to do, he's not my dad.

    Anyway when I landed and got service back, I had a ton of texts voicemails, but I only listened to a couple of them since they were basically all either Phil and the kids saying how much they miss me or my mom crying about how abandoned and she feels. I'm at my grandparents' house now and they've invited me to stay for the

    were relying on me to look after the kids when they both have to go back to work, and if I stay here in Wisconsin they'd have to take unpaid time off or use up precious sick days, or hire a babysitter, and I know they hate doing that.

    This whole situation has made me feel rotten, like a shitty daughter and sister, but I can't really talk to anyone irl about it since my friends are back in California spending Christmas Eve with their families. I guess I just wanted to get this off my chest anonymously/ask if I'm in the wrong here.

    If Mom is pregnant now, just wait until she gives birth and bestows all new responsibilities upon her high schooler!

    J. You're 18. Better to break the cycle now. You aren't responsible for their choices to have kids. Fortunately the cost of living in Wisconsin is much cheaper. This is a hard situation but you are clearly NTA. You should probably get out of that house sooner rather than later before you wake up at 28 as a full time caregiver.

    Stay in Wisconsin. You deserve a vacation away from your family. Why is your mother pregnant AGAIN? That's her choice, and not your problem. Rest and relax with your grandparents. Don't let your family guilt you into leaving until you're good and ready...which they were not when it counted at the airport.
